Check out the JEE Mains 2018 Eligibility Criteria to clear every single doubt coming in your mind.
According to this, the candidates who have scored at least 75% marks in the 12th class are only eligible for appearing in the JEE Mains exam.
So, if you can't appear in the JEE Mains exam, then you can can't get admission in any of the NITs or IITs.
If you haven't scored 75% in 12th, then you can go for the improvement exam or the NIOS exam.
Hope this will help.
All the best.

Try to be really an expert in one of the programming languages. Work for a company for some time to understand how a process driven organization works. And then develop your own product and get started with your start up.
If you want a job only then make your profile strong. Work for live projects, participate in competitions, develop your communication skills and confidence. It's always a good idea to first work for a startup. In the initial years, don't run behind money. Run behind gaining knowledge and skills. Once you have them job providers will be in search of you rather than you searching for a job.
